Simulation of the effect of intermittent flow in polycrystals on the basis of cellular automata and relaxation element method

Abstract

The simulation of the effect of intermittent flow in polycrystals is performed on the basis of cellular automata and relaxation element method. Each cell (representing element of a structure) has an ability to switch its state by discrete jump in stresses (or plastic deformation), prescribed by a definite relaxation element which is put in the center of the cell. Interaction of the field of internal stresses from structural elements, undergone plastic deformation occurs automatically, following the superposition principle. The results are in a good agreement with known experimental findings. © 2008 Springer-Verlag Berlin Heidelberg.
